To all/whom it may concem Be-it known that I, HowAfnojM, selling a citizen ofthe United States, and a resident of Alliance, in the county of Stark and State of Ohio, have invented a nev'v'and-Improved .Coal .Pocket, of which the following is a full, clear, and exact description.

. This invention relates to improvementsin coal pockets, an object of the invention being to provide a coal pocket having an i1nproved arrangement of pivoted chute, the atter when-in operativeposition,'spaced at its upper end from the wall; of the hopper,

struct the pocketas' to"contr0l theflow of coal and permit theloosening of accumulating lumps which wouldinterfere withthe proper operation of the pocket. v

A further object. is to provide a coal pocket, which can be conveniently utilized 7 for loading so as to direct the coal wherever desired into the vehicle being loaded, and which is of extremely simple construction, strong anddurable in use.

invention consists in certain novel features of construction, and combinations and arclaims. a

rangements of parts as will be more fully hereinafter described and pointed out in the In the accompanying drawings- '-Figure '1 is" a sectional plan view on the line 1--1 of Figure 2;

Figure 2 is a view in vertical'longitudr nal1 section on the line 22 of Figure 1; an o v Figure 3 is a view in front elevation of Figure 2.

1represents the bottom of an ordinary coal bin which directs coal into a hopper 2, the latter having at its lower rear portion an outlet opening 3 for the discharge of the coal onto a chute 4. The chute 4 is pivotally mounted on a transverse shaft 5 supported in hangers 6 and is composed preferably of sheet metal having channel bars 7 at its sides extending rearwardly and upwardl beyond the end of the chute and providbd with counter-balanced weights 8. r

If desired, I may also provide cables 9 ancing means.

This space between the bar 26 and theend of the other toolto dislodge lumps of coal which have clogged the outlet of the hopper, and

the bar 26 acts as a supporting bridge or guide for the tool so that the operator on the ground can easily manipulate the same to clear the passage and cause a free flow of coal from the ocket.

In-handling ituminous coal'having large 100 hopper affords an entrance for a poker or o -merely to break an arch or dislodge anacchute having its end adjacent the hopper spaced from the hopper and providing a free opening or entrance for a tool to dislodge accumulating piles of lumps, a free flow can be maintained or at least restored from time to tlme'r Also this operation can be accom-v plished with a minimum of breakage of the lumps-as it is desirable to maintain the? lumps as large as possible and the use of the poker is not .tobreak up'lumpsbut cumulation which stops the flow. In order to provide this passage or free spacebetween the chuteand the end of the hopper it is obvious that the chute is open ended and the space will be amplefor the manipulation V of the .tool withoutallowing any coal to es- ;ca e through said opening or space.

t will be noted that the slide 14 is pro-. jected acrossthe hopper-cutting off the flow of coal but leaving a clear openingat-the top; In other words by positioning the slide as indicated a lump-can not blockthe clos- 1 ing movement of the side as the flow-is effec- 'tirely to the rear wall of the hopper.
